My wife and I had points for a $125 and a $100 gift certificate when they changed the point structure a few months ago. Our point value dropped $25 each. We cashed out for a $100 and $75 gift certificate. I haven't bothered with them since.
Last week I bought a Sony CD Walkman at Circuit City and I only had to pay the tax for my $100 new toy. Looking forward to flying with my music next week.
Milesource had its uses.
